US Sailing provides and manages services to facilitate safe competition for big boats in offshore racing. We offer products to improve the performance of boats, issue sail numbers that meet national and international standards, and have safety education training and certification opportunities.

US Sailing’s Safety at Sea Committee has conducted several independent reviews of sailing accidents over the years. These archived safety reports have been used to provide the latest updates and recommendations for best practices in safety equipment, rescue procedures and emergency planning.
